General annotation (Comments)

Function

Cytoskeletal protein involved in actin-membrane attachment at sites of cell adhesion to the extracellular matrix (focal adhesion) By similarity.

Subunit structure

Interacts with VCL and SRC (via SH3 domain). Interacts with GIT1, NUDT16L1/SDOS and TGFB1I1. Component of cytoplasmic complexes, which also contain GIT1, ARHGEF6 and PAK1. Binds ASAP2. Interacts with RNF5 and PDCD10 By similarity. Interacts with SORBS1, PARVA and PARVB. Interacts with NEK3 and this interaction is prolactin-dependent By similarity. Interacts with PTK2/FAK1. Interacts with PTK6 By similarity. Interacts with PTK2B/PYK2. Ref.3 Ref.5 Ref.6

Subcellular location

Cytoplasmcytoskeleton By similarity. Cell junctionfocal adhesion By similarity. Cytoplasmcell cortex. Note: Colocalizes with integrins at the cell periphery. Ref.3

Post-translational modification

Phosphorylated by MAPK1/ERK2. Phosphorylated on tyrosine residues during integrin-mediated cell adhesion, embryonic development, fibroblast transformation and following stimulation of cells by mitogens. Phosphorylation at Ser-244 by CDK5 reduces its interaction with PTK2/FAK1 in matrix-cell focal adhesions (MCFA) during oligodendrocytes (OLs) differentiation By similarity. Phosphorylation at Tyr-31 and Tyr-118 by PTK6 promote the activation of RAC1 via CRK/CrKII, thereby promoting migration and invasion By similarity. Ref.4 Ref.10

Sequence similarities

Belongs to the paxillin family.

Contains 4 LIM zinc-binding domains.
